Application filed November This invention relates to a device for wiping joints-5 ct lead pipes :t'or use in plumbing worli; its object is to systen'iatize and sinipli'l the labour wiping; joints, by provid ing mechanical means for perttorininp,- worlr which is usually done by slow costly hand proce il b modern standardized phnnbing accessories which require a wiped lead joint there is a considerable proportion which can more easily and more cheaply be manufactured in the work-shop instead of in situ, and my device is intended to accelerate and cheapen the production oi work oi? this kind.

To ell'eci iny improvements 1 use a devic involving the following elements i l rectangular framework of the nature oi? a bench or table carries centrally disposed along and over its top, a mandrel .or bar upon which are threaded and secured one or more lei'igths ol lead pipe, brass il'errules or the lil-Le to be united. The bar is provided at suitable intervals with loose collars and cotter slots for securing the pieces of pipe or ferrules in any desired position. Means for holding, the pieces in correct alignment centrally and longitudinally are also provided. l-lingable bearings at intervals lengthwise of the mandrel enable the bar to be raised for the insertion of the work so that several joints may be wiped ahnost siinultaueously.

Under each transverse division is arranged a slide having a motion riglitaiug'ular to the bar and currvinu a pivotal. grooved ineinber holdiiw' :he wiping cloth and solder, so that the solder may be applied to the lead pipe at any angle and at any radius according to the position of the slide and the angle oil the member .lioli'lin the wiping cloth in relatiiui to the bar, The i'nandrel is pro vided with a hand crank for slowly wiping the joints and has also a treadle device for rapidly trimming oil the work.

lln operation the device is used as follows: The work to be jointed and soldered is mounted upon the shaft 9 and there secured. The operator then takes hold of the pivotable solder holding wiper 19 and places same in contact with and on the underside oi the joint to be wiped, the wiper 19 being; held at an angle or about twentj de grees and a little towards the operator. Molten jointing metal is then poured over the joint at iil'lfi sau'ie time as the work is e, 1926. serial no. 14t7,31tl.

slov-Jl revolved by the shaft U which is driven by either :loot pedal or a helper. its the molten metal poured over the joint it is wi pod and tornied into place by the inanipulotion oil the wiper it) being); swiped (or struck with a. sweeping; motion) over the poured metal which rjliicltljv cools and hardeiis inti'i place, the groove in the wiper block 19 g" I l to the finished joint the necessary reinforcement o'l nietal is usual in a himd wipod joint of this character.

The wort: being centrally iosed over the bench all excess metal. ch escapes through the groove of the wiper block 19 before conii hardened is caught by the bench and car readily be rejjilaced in the melting la'lle tree from all ioi-ei :11 sub st nces, which is not the case when work o't this character is performed out oil the shop; ther fore there is a saving both oil. metal and time by the use oil this inuchine.

Referring to the drawings which form part o'l the application, Fin, 1 is a plan. Fig. is a side elevation, l 3 an end elevation, Fig. l a detail 0' device as applied at the end of the iFra1nework to an elbow. Fig. 5 a sectional view of the pivotal solder holder, the two latter figures being to an enlarged scale.

Taking the drawings in detail these show a simple embodiment of my invention mounted upon a rectangular wood Illllllfi ti of the nature of a table or stand, on the top side of which are secured three hinpgablc bearings 7 carried by the transverse. bloclu-a A shaft 9 ol? the nature of a inaiulrel. is supported in the bearings 'l', and is revolvable by the humid crank 10.

The lirainework is, for the convenient manipulation of the work, divided in three compartments 11, '12, 13. Immediately below the shaftin each compartment is horizontally slid-able member 14-, 15, 1.6; the centre one being drawn out as shown at 15. Each of the slidable members carries a erankec spindle 17 which is free to pivot on the sides ot the slidable members at 18 and carries in turn a pivotal solder-holder 11.9.

The method of securing; the two pipes which are beingunited by a wiped lead oint at 20 is shown by the enlarged part sectional drawing Fig. 4; which also illustrates how a bend or elbow pipe 531 is inzniipulated, the usual b ass ferrule or nipple P22 held. cen tral about the sh,,.. 1 9 by the adjustable cone l? the pipe holding r Iii ltltl llltl 23, the latter being secured by the nut 24:, 25

being a short length of pipe (shown in section) and acting as a distance piece between the cone 24 and the compressible washer 26 also secured on the shaft by a nut 27.

A treadle 28 operates the lower crankshaft 29 and the gear wheel 30 and pinion 31 in order to affect quick revolution of the shaft when the work is being cleaned off by wire brush.

v Having now particularly described my invention, what I desire to secure by Letters Patent, is:

1. A plumbers joint-wiping device comprising, a rectangular framework, a revolvable bar positioned above the top of said framework and supported therefrom, a plurality of hingable bearings carried by said framework and supporting said bar, means for revolving said bar, a sliding member positioned below said bar and movable in said framework rightangularly to said bar, a cranked spindle carried by bearings in the sides of said sliding member, the axis of said spindle being parallel to that of said bar, a solder-holding member pivotal on said spindle.

2. A pl'umbers joint-wiping device comprising, a rectangular framework, a revolvable bar positioned above the top of said framework and supported therefrom, a plurality of hingable bearings carried by said framework and supporting said bar, means for revolving said bar, a sliding member positioned below said bar and movable in said framework rightangularly to said bar, a cranked spindle carried by bearin in the sides of said sliding member, the a :;is of r-zlid spindle being parallel to that of said bar. a solder-holdin member pivotal on said spindle, means for increasing the rotational speed of said bar, said means including a foot treadle, crank shaft: and gear wheels.
